And Finally the Left Fielders

In previous posts, I took the Revised Zone Rating (RZR) and Out-of-Zone Plays (OOZ) metrics listed at FanGraphs
and converted them to runs based on an algorithm developed by Colin
Wyers a few years ago. Links to these posts are provided below:

Now, I'm going to to do the run conversion for left fielders. Table 1
below contains the following information for 15 MLB left fielders with 800
or more innings in 2012:

Inn = Innings

RZR = Revised Zone Rating

OOZ = Out-of-Zone Plays

PIZAA = Plays in Zone Above Average

OOZAA = Out-of-Zone Plays Above Average

PMAA = Total Plays Above Average

RSAA = Runs Saved Above Average

Twins left fielder Josh Willingham led the
majors with +9 Runs
Saved Above Average. He was followed by Alex Gordon of the Royals and Desmond Jennings of the Rays at +8. The worst left fielder by this metric was Matt Holliday of the Cardinals (-20). No Tigers are included in the table because they did not have anyone with played 800+ innings. For what it's worth with such a small sample size, Andy Dirks (+2) and Quintin Berry (+1) were right around average on this metric in under 500 innings.
